Well? Dinesh D'Souza never really answers. But at the time Giovanni Gentile the argument was between left collectivists and right collectivists over who version of socialism was the better, the global or the national version, for that in essence was their only major difference--in all other respects they were collectivists again individualists, freemarkets and liberal democracy.
Those on the left who beg to differ, listen to the video and the ideas of Giovanni Gentile and tell us where you disagree with him and why. Good luck.
